Should I enroll at the local community college just to get laid?

It's been over a year since I last had sex. I'm not hideous, but certainly not hot, and I don't know how to approach girls. I do dress nice, though.
I have a BA from the best university in my state, and I was in the Peace Corps. I'm now looking at top grad programs.

So, I'm thinking I'll enroll in a course I'll benefit from - maybe a language - then get involved with geeky student groups like anime or whatever, and then as the educated/successful guy hit on the underachieving otaku geeks and ghetto Latina girls
the whole thing should be an ego stroke, which will be nice since I feel pretty shitty about myself right now

whaddya think? Advice?
